The CSS column-gap property sets the gap between columns for block elements which are specified to display as a multi-column element. Currently no browsers support this value (maybe Firefox 4.0 and IE9), but some browsers have their own vendor extensions (see below).
Values[]
| Value | Description |
|---|---|
normal |
Default value, depends on the user agent. |
<length> |
Specifies a length value for the space between columns. Values must be positive. Examples of lengths are px, cm, etc.

CSS example:
body {
column-count:2;
column-gap:50px;
}
